Question about my Lovebirds?

I have two Lovebirds in a very large cage. I also have a screened in front porch. I was wanting to set their cage out on my porch and leave them out there this summer. It rarely gets below 65 in the evenings where I live. On the other hand, it gets up to 100 on some days and the humidity is sometime unbearable. I have a little bath for them in their cage for them to get wet and clean themselves. My question is, is it ok to leave them outside? They are 100% safe from any type of predator. The only thing I was concerned about is the humid and hot weather. Thanks in advance for any answers or advice :)
